Save network bandwidth by playing video at a lower resolution on Windows

Windows 11 comes with a setting called Save network bandwidth by playing video at a lower resolution, which helps you save your bandwidth while playing video in some apps. Here is how you can enable it on your Windows 11 computer and start saving some bandwidth while enjoying your favorite movie.

Microsoft Store offers so many apps that often allow you to play videos. Some apps play videos at high resolution to provide the best possible experience when others play low resolution. If you have a high-speed internet connection, most apps often play videos at high resolution by detecting that. However, if you want to watch the video and save the bandwidth, you need to opt for a low resolution. As most of the apps do not have the option to switch between various resolutions, you can use this in-built functionality of Windows 11.

You can enable this setting using Windows Settings and Registry Editor. Here are both the method, and you can follow either of them according to your convenience.
